Application led November the pilots either in station or in full flight. y

This controlling handle is of the kind which comp-rises a hand wheel the rotation of which operates the control of the transverse stability and the longitudinal displacements of which towards th-e front or rear ensure the controll of the longitudinalstability.

The particular feature of the` invention resides in the fact that the whole of the controlling handle, that is, the wheel with its chains, can be angularly displaced by rotation about the axis of the tubular shaft of the transverse stabilitjgv control, without rota-ting the said tubulary shaft, the said wheel being locked in one or the other of the two extreme positions it is adapted to take, positions in which it is situated either in front of one Vor in front of the other of the two pilots, v

The following description, in connection with the appended drawings which are given as an ye.\;a1nple only, will help `in clearlyv understanding the manner in which the invention is carried out.

Fig. l. is a diagrammatic section of the whole of the movable controlling handle.

Fig. 2 is a transverse section along 'of F ig. l;

Fig. 3 is a view on an enlarged scaleof the portion of Fig. 1 showing the controlling chains. f

In the particular manner of carrying out the invention illust-rated in these drawings, the whole of the device, that is, the wheel o, its spindle, o, the sprocket wheel. o, and the casing o are adapted to rotate through a certain angle about the axis aan which' is also that of the tubular shaft ci of the control of the warping and of the tlll@ 6 of the s, `19,21. seran no. 513,720.

control of the depth. The 'hand-wheel can `therefore be brought in full flines, Y, Fig. 2 or in broken lines,

two pilots; vDuring this displacement,

which takes place ,in the `directiolni of the in the position shown between the tubular pivotA and the casing so that the latter inay be rangu'larly displaced with reference to the pivot without causing the same to rotate.

.it is essentially necessary to provide a locking arrangement maintainiiig the controlling handle in one or the other 1of its working positions. This may be accom-f plished, for instance, by means of a rbolt L engaging' `an upright or fixed part i of the body and carried by the collar j; the latter is secured by a slidingfkey `'or by grooves 'on the 'tube el (whiclris a prolongation 'of the tube. e) integral with y'the casing o; ln these conditions when the bolt 71y is in engagement, `the casing and therefore the hand-wheel are locked 'i'otaltionally It is to be ren'iarked however, that they can take an axial disL placement owing s to the sliding key or groove. mounting.. This bolt can occupy one or the other of the'positions /L orI 71.1 accordingy to whether the hand-wheel is at V or Vl. i n f y rl'he hand-wheelbeing locked in one position the control for warping, depth and direction takes f place in the following manner: l

llfarpiag.'l`lie rotation of the handwheel'` about the axis YY produces, by means rof the pinions b, ofthe two chains ,f and of the pin'ions y, the `rotation of the shaftk d of the `control of the warpino'. This shaft can only turn, without displacing itself in ay direction parallel to its axis.

Depffz.-'l`l1e whole 0f the casing c and of the hand-wheel V can be displaced axially and this movement is transmitted by projecting pieces or a collar mto the shaft e of the control of the depth rudder.

Drcotz'oa-f-This same shaft e receives an independent movement ot rotation besides its movement oi' translation, and this movement is tiansinitted to the direction rudder. For this purpose the rudder bar transmits its rotational movement to a plate 7a grooved orv mounted with a sliding key upon the shaft e and rotating within a fixed portion l of the body. Movements oi plate are transmitted to the direction rudder by suitable connections (not shown) between the rudder and said plate, and since these connections are well known in the art and 'form no kpart oi the present invention a detailed description of the same is unneeessary.

Vilhat we claim 'and desire to secure by Letters Patent is:

o l. il single hand-wheel support for the control of the warping and of ythe depth of aeroplanes and other aerial apparatus comprising means tor causing the support 'to pivot atits lower end so as to be able to bring the wheel in front of one or the other of two pil-ots positioned side by side without exerting any action upon the Controls, means for controlling the warping b-y rotation oft the hand-wheel, and means 'tor operating the depth rudder by a longitudinal displacement of the hand-wheel along its axis. l.

2. A single'hand-wheel support 'tor the control ofV the warping and oi the depth ot aeroplanes andother aerial apparatus, Coin- -prising an arm, a pivot at the. bottom ot the arm, a. hand-'wheel arranged upon the easing so. as to be able to rotate. about the pivot, ine-ans li'oi' controlling the warping by rotaiion'of the hand-wheel, and means for rontrolling' the' depth rudder by longitudinal displacement ot' the hand-wheel along its axis.

3. A single hand-wheel supportl toi' the control of the-warping and of the depth ot' aeroplane-s and other aerial apparatus coinprising an ai-ni forming acasring, a tubular pivot Iat the bottom oit-the casing and about which the latter can, be angularly displaced, a hand-wheel mounted on the upper part ot' the Casing, a shaft for the control warping passing through the tubular pivot, means :tor connecting the tubular pivot with the shaft so that said pivot in its rotarymotion rota-tos said shaft and may slide longitudinally with reference to the latter, means for conneet-ingthe hand-wheel with they tubular pivot so that the rotation of said hand-wh eel the tubular pivot will rotate thereby con` trolling the warping while in causing'the whole of the casing and the hand-wheel to rotate about thel tubular pivot in order to bring the hand-wheel before the one or the other ot the .se-ats of the two pilots no action will be exerted upon said tubular pivot, and

meaiis lor controlling the depth rudder through sliding motion ot' the Casino', hand-wheel, and tubular pivot along the axis olf said shaft,

et. A single hand-wheel support for the control oft the warping and oit' the depth of aeroplanes and other aerial apparatus, comprising a casing, a tubular pivot arranged at the bottoni ol' the casing and about which the latter can be displaced through an angle, a hand-wheel mounted at the upper partof the casing, a shalt tor the contro-l of the warping passing through the tubular pivot, means for connecting the tubular pivot with said shaft soi that said pivot inv its rotary motion rotates said shaft and may slide longitudinally with reference to the latter, l

pinions secured to the hand-wheel spindle and located in the casing, pinions securedto the tubular pivot, chains connecting the pinions, a long key connecting the't-ubular pivot with the shaft, 'ball-bearings inter'- posed between the tubular pivot and the casing so that the. casing may be angularly dis'- placed with reference to the pivot without causing the same to rotate, saidy casing and pivot being movable together in a longitudinal direction, a tube connected with the casing and .transmitting longitudinal displacements ot the whole ot the easing anil ot the hand-wheel to the means for the control ot the depth rudder.

5. A single ihand-wheel -tor thel control of: the warping and ol the depth voit' the aeroplanes and other aerial apparatus comprising means for causing the support to pivot at its lower end so as to be able to bring` the. hand-wheel before one or the other of two pilots positioned side by side with this pivoting motion. having no influence upon the' controls, means for controlling the. warping through a rotation of the hand-wheel,means for `controlling the horizontal `rudder through longitudinal displacement, that to say a motion towards the front or rear, of the hand-wheel along its axis, and means for lockingv thel support in one o-tl its two positions. y
